[][src]Struct tokio_io::io::AllowStdIo

pub struct AllowStdIo<T>(_);

A simple wrapper type which allows types that only implement std::io::Read or std::io::Write to be used in contexts which expect an AsyncRead or AsyncWrite.

If these types issue an error with the kind io::ErrorKind::WouldBlock, it is expected that they will notify the current task on readiness. Synchronous std types should not issue errors of this kind and are safe to use in this context. However, using these types with AllowStdIo will cause the event loop to block, so they should be used with care.
